Method and system of opening and closing door of vehicle

Abstract

A system of opening and closing a door of a vehicle includes a tap sensing type smart key configured to collect and transmit sensed information corresponding to tap pressure applied from the outside. A signal transmitter is configured to support transmission of the collected sensed information or a message corresponding to the sensed information.

What is claimed is: 
     
         1 . A tap sensing type smart key comprising:
 a tap sensor configured to collect sensed information corresponding to at least one of pressure and audio signals depending on a tap operation applied from the outside; and   a signal transmitter configured to support transmission of the collected sensed information or a message corresponding to the sensed information.   
     
     
         2 . The tap sensing type smart key according to  claim 1 , further comprising a card shaped case configured to accommodate the tap sensor and the signal transmitter therein. 
     
     
         3 . The tap sensing type smart key according to  claim 2 , wherein the tap sensor senses set pressure patterns or audio patterns depending on tap operations generated at an outer portion of an object into which the card shaped case is inserted. 
     
     
         4 . The tap sensing type smart key according to  claim 1 , wherein the tap sensor is activated at the time of receiving a scan signal from a vehicle within a set distance between the vehicle and the smart key. 
     
     
         5 . A vehicle supporting opening of a door, comprising:
 a signal transceiver configured to receive sensed information corresponding to at least one of pressure patterns and audio patterns, wherein the at least one of pressure patterns and audio patterns are generated where a tap sensing type smart key is disposed;   a controller configured to open and close at least one door depending on the received sensed information; and   a door opener/closer configured to support the opening and closing of the door depending on a control of the controller.   
     
     
         6 . The vehicle according to  claim 5 , wherein the signal transceiver transmits a signal for scanning the tap sensing type smart key at a set period of time or in real time. 
     
     
         7 . The vehicle according to  claim 5 , wherein the signal transceiver receives a command requesting to open the door of a specific position from the tap sensing type smart key. 
     
     
         8 . The vehicle according to  claim 7 , wherein the controller opens the door corresponding to the command. 
     
     
         9 . The vehicle according to  claim 5 , wherein the controller compares the sensed information with a reference signal and opens and closes the door depending on the sensed information in the case in which the sensed information is valid. 
     
     
         10 . The vehicle according to  claim 5 , wherein the controller compares the sensed information with a plurality of reference signals and opens and closes at least one door depending on a kind of reference signals that are equal or similar to each other. 
     
     
         11 . The vehicle according to  claim 10 , wherein the controller opens and closes only a driver's side door, opens and closes all doors, or opens and closes a trunk door depending on the sensed information. 
     
     
         12 . A system of opening and closing a door of a vehicle, the system comprising:
 a tap sensing type smart key configured to collect and transmit sensed information corresponding to at least one of pressure patterns and audio patterns due to tap operations generated in the vicinity thereof; and   a vehicle configured to open and close at least one door depending on the sensed information received from the tap sensing type smart key.   
     
     
         13 . A method of opening and closing a vehicle door, the method comprising steps of:
 receiving a tap signal from a tap sensing type smart key, the tap signal corresponding to at least one of pressure patterns and audio patterns due to tap operations within a reference distance from a point in which a vehicle is positioned; and   opening and closing, by the vehicle, at least one door depending on the tap signal.   
     
     
         14 . The method according to  claim 13 , further comprising, comparing, by the vehicle, the tap signal with a reference signal,
 wherein the opening and closing of the at least one door includes opening and closing the at least one door depending on similarity between the tap signal and the reference signal.   
     
     
         15 . The method according to  claim 13 , further comprising, comparing, by the vehicle, the tap signal with a plurality of reference signals,
 wherein the opening and closing of the at least one door includes opening and closing the at least one door depending on a reference signal that is equal or similar to the tap signal.   
     
     
         16 . The method according to  claim 15 , wherein the step of opening and closing of the at least one door includes at least one of:
 opening and closing only a driver's side door depending to the reference signal;   opening and closing only all doors of the vehicle depending to the reference signal; and   opening and closing only trunk door of the vehicle depending to the reference signal.
